To'all whom 'it may concern:

Be it known that i, THOMAS @inimmaona, a citizen ot' the United States.residing aty Salem. in the county of Columbiana and State ot Ohio, haveinvented certain new and useful 1lnprm'einents in Lawn-Spray Nozzles;and I doherehy declare the following to be a full. clear, and exactIdescription of the invention, such kas will enable others .skilled inthe art to which it appertains to malte and use the same.

My invention relates tonozzles for spreading water, has especialreference to spray nozzles used for spraying water u on lawns and thelike', has for its object a cheap, etlicientl and durable structure forthe purpose, and consists in certain improvements in construction.-which will oe fully disclosed in the 'following speciicatiou and claims.

in the accompanying drawings, which torni part of thisspecification:HFigure l represents a side elevation of a spray nozzleFig. 2 a Vertical longitudinal section showing the lateral dischargepassages open or uncovered, and l ig. t. a like View showing saidpassages closed.

Reference being had to the drawings and the designating charactersthereon, the numeral l indicates the body of the nozzle, 2 a stein to heinserted in the ground to sup- 1port the nozzle while inuse. 5S thereceiving,r end provided with au internal screwthread Lifor attachmentto a hose., not shown. 5 a chamber at the discharge end of the nozzleprovided with a cylindrical Nall (i in which are lateral dischargepassages 7. of which there may he any desired nuinoer, and in the end 5%is a discharge opening 5), which is controlled h r a conical valve l0adjastahl)v supported on a stein ll which extends through the chamber 5and is secured to the-hotlyY l at l2.

hu'roiuuliug the wall ti, is au annular sleeve 'lil provided with aninteral -screw thread ll which engages a threaded portion l?) on thebody of the nozzle and on which the .sleeve is vertically adjustable tocontrol lthe discharge of watt-r through the lateral passages T. hymeans4 o'l" a horizontal and inwardhY extending` annular valve or lip ltwhose width is equal to the diameter of the passages T.- and ou theupper end otx the sleeve adjacent to the. valve lo is an out.- wardlj`tiered or hert-led annular surface 1T, against which the water issuinglroxu the passages T impide-es and is disintegrated or jected insubstantially the saine direction iis the water discharged troni thepassages 7.

The roluiue of th'e dischargeof Water may he regulated from the maximumcapacit-y of the. nozzle to a spray of an;y desired ineness hy theadjustment of the valves 1l) and 16, and hy the use of either valvesingly or hy using the two in conjunction with each other.

lt'is obvious that changes may be made in the details oi' constructionwithout departing from the spirit4 of my invention, For example, thepassages T, may he drilled atan angle on one. side of the center of thechainher 5. which will cause the water to strike the ir. line 1T at anangle and impart a cir-v cular motion to the water as it is discharged.

llaving thus fully described niyinventlon, what l claim is: j

l. A. spray nozzle having an openin in the discharge end thereof, avalve adjust,-l ahle at a right. angle to the plane of Said opening,lateral discharge passages adjacent; to said end, au outwardly flaringVannularv surface adjacent to said passages, and. means tor controllinglthe discharge of water through the late al passages. l

2. .t spray nozzle having an openingin 'its discharge end, aconiealvalve in said opening and adjustable aty a right angle to theplane of the opening, lateral )assage's adjacent to said end, and an ainstable ysleeve having an outwardly flaring annular surface adjacent.to said passages.

3. .spray -nozzle having an opening in the discharge end thereof, aconical valve adjustable in said opening', lateral passages adjacent tosaid end. an adjustable sleeve provided with an annular valve to controlthe discharge of water through said passages, and having an outwardlyflaring annular surface at its cud and opposite said passages. i
